Question

A picture frame is hanging by two vertical strings. The tensions in the strings are 3.8 N and 4.4 N. Find the weight of the picture frame. ​

Answer 1

Answer:

x = ? and Fy = ?

Fx = F cos θ

Fx = 50 × cos 30

= 50 N × 0.866 (˙.˙ cos 30⁰ = 0.866)

Fx = 43.3 N

Similarly, Fy = F sin θ

Fy = 50 × 0.5 (˙.˙ sin 30⁰ = 0.5)

Fy = 25 N
